"A few weeks ago, we were a bit surprised to learn that the AMG version of Mercedes’ new SLC-class roadster—it replaces the SLK-class—would be powered by the engine found in the AMG Sport models of the C- and GLE-classes, the C450 AMG and GLE450 AMG. (AMG Sport was launched to neatly split the difference between regular Mercedes vehicles and full-bore AMGs.) AMG hadn’t offered a six-banger in many years, and the twin-turbocharged V-6, while an impressive powerplant, doesn’t adhere to Affalterbach’s “One Man, One Engine” gospel, whereby one technician assembles a complete engine from start to finish.

But the Mercedes-AMG SLC43 won’t be an exception—it actually sets a precedent, as the AMG Sport models will be rechristened and moved into the AMG lineup properly. The Mercedes-Benz C450 AMG will become the Mercedes-AMG C43, and a Mercedes-AMG E43 will launch later this year. Further models will follow.

This is interesting as it now means that the C 450 will become a full fledged AMG Model this is good news for some, but not for others as it removes the one car one machine mindset that mercedesamg has traditionally held.
